Enhancing Urban Resilience through Strategic Parking Pricing in Jakarta’s Bus Rapid Transit Corridors

Sanda Arifianto — 2024-10-01

Although Jakarta has invested in various mass transport systems, these efforts have not successfully reduced private vehicle use. Due to this, this study aims to analyze the impact of implementing TransJakarta bus rapid transit corridor-based high parking tariffs on travel mode choice, including road- and rail-based public transport, ride-hailing, taxi, car, and motorcycle. Involving 478 private vehicle users and implementing a nested logit model, some variables, including respondents’ income, travel time, egress time, parking costs, parking distance, travel cost, and parking surcharge, are considered to understand to what extent these variables influence the use of proposed travel mode in the future. The nested logit model shows that not all variables significantly influence travel mode use, specifically related to rail-based public transport choice among motorcyclists. Meanwhile,
parking distance insignificantly influences the choice of all travel modes except cars among car users. The results also indicate that increasing parking tariffs insignificantly influences the likelihood of both motorcyclists and car users shifting to public transport. Motorcyclists and car users tend to continue using motorcycles but change parking locations with higher tariffs. Additionally, some shifts towards ride-hailing services and TransJakarta Bus Rapid Transit are found, meaning that there is potential for these alternatives to play a significant role in reducing private vehicle use. Based on the model results, additional push-based policies, such as the odd-even license plate rule, are necessary to effectively support the transition from private vehicle use to public transport. Implementing these policies is expected to significantly contribute to reducing traffic congestion and promoting a sustainable and resilient urban environment.

Field Study of Deposit and Erosion Patterns around Pandanus Clusters Driven by Hydrodynamic Waves: A Preliminary Field Investigation

Nizam — 2024-10-07

Coastal zones are inherently dynamic, often resulting in long-term cumulative impacts such as erosion, which can potentially escalate into disasters. Discussions regarding nature-based solutions, particularly the utilization of coastal forests, have gained prominence due to their environmental benefits. This paper investigates the role of vegetated coasts in mitigating the effects of wave attacks on land, focusing specifically on Coastal Pandanus species. We conducted a systematic monitoring effort to quantify land changes directly around these species in the field. The southern coast of Java, characterized by significant coastal processes, served as the investigation site. We monitored the changes in the foredunes of eight Pandanus clusters identified along a 1 km stretch of the Pandansari and Samas coasts in the Special Region of Yogyakarta, Indonesia. Our systematic monitoring, conducted biweekly from September to December 2023, involved precise measurements of land elevation, sediment deposition, and erosion around
the Pandanus clusters. We utilized manual leveling surveys and installed erosion pins to enhance the precision of our topographic assessments. These monitoring techniques allowed us to thoroughly examine the relationship between Pandanus cluster characteristics and coastal processes. Our findings illuminate the pivotal role of Pandanus clusters in shaping coastal profiles, which depend on cluster area and growth characteristics. Additionally, we underscore key points regarding their success rates, limitations, and future strengthening efforts through the implementation of this nature-based solution. This research contributes to a deeper understanding of the complex interactions between coastal dynamics and vegetative elements, paving the way for informed coastal management strategies in the future.
